Bells of Coronado

The owner of the El Coronado mine is ambushed on the road into town by thieves, who steal a wagon full of uranium ore. The owner is found by linemen of the Coronado Light and Power Company, but dies at the town's doctor's office before regaining consciousness.

The insurance company that has insured the ore hires Roy to determine whether the wagon accidentally left the roadway and if the ore fell into the Coronado Dam reservoir. With the help of the town's doctor, Roy takes a job as a lineman with the power company,

The thieves try to steal a second wagon load of uranium, but Roy gives chase and is able to wrest the ore from the thieves. The thieves steal the second load of ore after it had been taken to the warehouse. Roy discovers that the uranium will be delivered to a dry lake bed where a foreign government will land an airplane to collect it. Roy has to rush to stop the plane from departing with the uranium.^[1]
